Labour ministers are giving Winston Peters a nine out of 10 for his time as Acting Prime Minister, but National leader Simon Bridges said he had "bumbled" and focused on sideshows such as the Australian flag at the expense of the economy.
Peters will hand the reins back to Prime Minister Jacinda Ardern at midnight tomorrow when he flies to Singapore for international summits.
Bridges said Peters had not been as bad as some had feared but nor had things gone as smoothly as Labour ministers claimed. He pointed to Peters' comment that the "jackals" would come for deputy leader Paula Bennett and that Bridges would not last until the election, as well as Peters' ongoing crusade against Australia's flag.
"I think he has performed as I expected. He has bumbled along, but ultimately he hasn't changed the course of his direction. He's focused on side issues like talking much more about me, flattering in a sense, and Paula Bennett but not talking about the economy, the decline in business confidence, on job insecurity.
"These are the things he should be judged on and he has done nothing.
